  • • Partners Capital achieved final close of Merlin IV, a private equity co-investment fund, with over $1 billion in commitments from global family offices and institutional investors across North America, Europe, Asia, and Africa.
  • • Merlin IV represents the fourth and largest fund within Partners Capital's co-investment platform, launched in 2019, focusing on lower-middle-market and middle-market buyouts where PE managers require reliable equity commitments under compressed timelines.
  • • Partners Capital manages over $70 billion in assets under management and positions co-investment vehicles as solutions addressing market demand for speed and certainty in deal sourcing, with individual transaction commitments typically ranging from $25 million to over $100 million.

Summary
Pantheon, a leading global private markets investor with $85 billion in assets under management, successfully closed its inaugural private equity Collateralized Fund Obligation (CFO) at $1 billion, exceeding its initial fundraising target of $750 million. This structured product bundles a mix of private assets, including stakes in secondaries funds, co-investment strategies, and seeded private equity positions, creating a tradeable instrument that provides liquidity to investors holding illiquid private market commitments.

Concurrently, Partners Capital Investment Group announced the final close of Merlin IV, a private equity co-investment fund with over $1 billion in commitments. The vehicle marks the fourth iteration of Partners Capital's Merlin platform, originally launched in 2019, and represents the largest fund raised within the series to date. The fund attracted capital from global family offices and institutional investors spanning North America, Europe, Asia, and Africa, underscoring sustained institutional demand for co-investment structures in the current market environment.

Both closings reflect structural shifts in private equity capital deployment. Pantheon's CFO addresses liquidity constraints for LP portfolios by securitizing LP interests, while Partners Capital's co-investment model positions the firm as an aligned equity partner alongside PE sponsors in single-asset transactions. Merlin IV focuses on lower-middle-market and middle-market buyouts, where PE managers increasingly require reliable equity commitments delivered under compressed timelines. Individual transaction sizes typically range from $25 million to over $100 million, enabling Partners Capital to provide sponsors with speed and certainty in a deal environment characterized by multiple transaction types and geographies.

Partners Capital CEO Arjun Raghavan emphasized that Merlin IV's oversubscription reflects the platform's ability to source distinctive opportunities and function as a trusted, agile partner to leading PE managers. These dual closings—totaling approximately $2 billion in capital deployed or committed—highlight institutional investor appetite for layered private equity solutions that address both portfolio liquidity needs and direct transaction participation at scale.
